I have a button called AddItem so i want whenever the button is got clicked new row shud be inserted on the table forexample when page is loaded there is no any row when user click the button one row shud be added when second time he clicks another row shud b inserted in the table control but the problem is at first time it inserts the row bt whn i click second time no row is inserted it shows only one row no matter how many times u click the button. I have addRow method in button click event which adds the row in the table when called. this situation is in c#. Actually i can make this in javascript but the problem is javascript cant create server side controls for example asp:textbox nd so on . i need to access the controls in each row through c# code so i cant achieve all the objectives in javascript. I hope u got understood wht the prob is.. I just want there shud be a function like addRow which adds the row in table when it is called in C# code any help will be greatly appreciated Aftab Ali Shaikh
